If mobile navigator dragscroll is invoked with a higher vertical scroll than horizontal, it should cancel

Basically, if invoked, the drag scroll listener allows you to go to a specific page or post, or something like that. However attempts to scroll up when starting from the bar will cause the page to ajaxify elsewhere, which is not the desired effect.

If the vertical scroll is > horizontal scroll, it can be assumed that it was meant to be a scroll up and so we can do nothing instead.

For small navigations (where horizontal scroll might be too small), perhaps we can adjust the logic so that the vert>horiz check is only triggered if vert > 2x navbar height
